Abstract Rice husk is an abundant and underutilized agricultural by-product in Indonesia. The silica contained the waste could be used as a substitute natural for various purposes. extraction of from rice (RH) has been done using sol-gel method without involving high energy. Extraction was carried out with KOH at concentrations 7, 10, 13% 90, 120, 150 minutes. Experimental results showed that h...

Abstract The physical properties of pure CuO and Pb doped thin films, deposited on glass substrates by a sol-gel method, were investigated. Structural analysis revealed the polycrystalline nature Pb:CuO composite films with monoclinic structure, crystallite size decreased ranged from 36.78 nm to around 21.5 nm. SEM images showed that doping concentration affects surface morphology composites. a...

ag/tio2 photocatalytic nanoparticles by two methods, the sol – gel using a reducing agent and spattering was produced. crystalline phase of titanium dioxide was investigated in both. ag/tio2 peak in the sol – gel method at temperatures of 300,500 and 6000c were studied. ag/tio2 peak at different temperatures were determined using the spattering. xrd patterns of calcined this is tio2 and ag/ tio2.

This study aimed to optimize and evaluate a thermoresponsive ophthalmic in situ gel containing curcumin-loaded albumin nanoparticles (Cur-BSA-NPs-Gel). Albumin nanoparticles were prepared via a desolvation method, and the gels were prepared via a cold method. The central composite design and response surface method was used to evaluate the effects of varying Pluronic F127 and Pluronic F68 conce...
